1. Aircraft Icing Forum Presentation

   

   Discussion

   I had the honor of doing the first presentation for the FAA Aircraft Icing Forum

   The Aircraft Icing Forum, hosted jointly by Cris Bosetti (FAA) and Dr. Peter Struk (NASA), provides a recurring monthly space to discuss aircraft icing research, technology, regulation, and related questions and challenges. The purpose of this forum is to provide an opportunity to share information, improve visibility, make connections, and advance the overall approach to aircraft icing knowledge and safety.

   The presentation "Aircraft Ice Protection in the NACA Era" is available in either LibreOffice or pdf format:

   Discussion

   Review of the Cylinders thread so far

   In the Cylinders thread, we saw:

   • A pioneering analysis of water drop impingement on a cylinder (NACA-TN-779)
   • The most cited aircraft icing publication, with more detail of water drop impingement on a cylinder, and the rotating multicylinder instrument ("Mathematical Investigation of Water Droplet Trajectories")
   • In flight icing measurements and an icing severity index (NACA-TN-1393)
   • An additional way to estimate drop size on a fixed cylinder (NACA-TN-1424)
   • Nine icing instruments compared (NACA-RM-A9C09)
   • The ability of the multicylinder method to determine drop distribution was questioned several times …
